Crown thinning is an advanced pruning operation normally carried out on hardwood trees by professional arborists. It involves removing dead and dying branches, branches which are rubbing together and general weaken the structure of the tree. We also offer a crown reduction and a crown lifting service. Crown treatment is essential in fruit tree pruning.
The benefits of crown thinning are
Our experienced team of tree surgeons will will ensure that the weaker branches of the tree are removed during crown thinning. We look for for tree branches which form acute V-shaped connections to the trunk of the tree and other branches. Such V-shaped connections form a bark wedge. These bark wedges will weaken the connection presenting a serious hazard to public safety during storms and high winds. The removal of a V shaped branch connection will cause the remaining branch to grow stronger. Branches and multiple tree trunks on the same tree which form a U shaped connection are generally considered to strong and should not be thinned.
When crown thinning we ensure that any branches growing off another are less than 75% of the diameter of the root branch at the point of attachment. When crown thinning we ensure that we do not leave a collection of smaller branches, shoots and leaves at the very end of the branch ( known as lion tails). Lions tails will lead to epicormic sprouting and will eventually lead to uneven weight distribution in the branch, causing it to break off.
As a general rule, when crown thinning we never remove more than 25%-30% of the living crown. If more needs to be removed this should be done in successive years to ensure the health of the tree.
